Mendel's law of independent assortment has its basis in which of the following events of meiosis I?

Okay, everyone. Mendel's Law of Independent Assortment has its basis in which of the following events of miosis 1? Okay. So the law of independent assortment states that how one gene segregates its alleles does not determine how another gene is going to segregate its alleles. Remember that the segregation of alleles is when the maternal allele goes into 1 gamete, and the paternal allele goes into the other gamete for, let's say, gene number 1. But how gene number 1 does that doesn't determine how gene number 2 is going to do that. So let's have a look at our answer choices. We're trying to figure out when this is going to happen in meiosis number 1. Okay? Answer choice a says the synopsis of homologous chromosomes is going to be the basis for independent assortment. Remember that the synopsis of homologous chromosomes is going to lead to crossing over and the exchanging of genetic material. But it actually doesn't have anything to do with independent assortment. So this is not the correct answer. Answer choice b says, crossing over of homologous pairs of chromosomes has its basis or is the basis for independent assortment. Again, crossing over, synapsis, exchanging of genetic material between chromosomes has nothing to do with independent assortment. Answer choice c says, the alignment of pairs of homologous chromosomes along the middle of the cell is the basis for independent assortment. Well, if you think about it, how the chromosomes align themselves in metaphase is random, And how they align themselves is going to be how they are separated and into which of the gametes they're going to go. So it is random. And this is going to be the basis for independent assortment, because how these homologous chromosomes line up is random. It can change every single time, but how they separate is independent of each other. So this is a great example, or this is a great answer because if you think about it, it's called independent assortment. Just thinking just think about the homologous chromosomes assorting themselves along the metaphase plate, and it they're doing this independently of one another. Okay? So So independent assortment. So this is a great answer. Let's rule out answer choice d. The division of cells during cytokinesis is the basis for independent assortment. Well, by this time, those chromosomes and those alleles have already independently assorted themselves. So it's already done by this point, so this is not the correct answer. Answer choice c is the correct answer. Mendel's law of independent assortment has its basis in the alignment of pairs of homologous chromosomes along the middle of the cell. Okay, everyone. Let's move on to our next video.
